You are using notebook? The battery usage you master? Long-term connection power use notebook, the battery should be how to save? Don't look too important question, actually affect the Dell Studio 1737 battery life, want to use notebook more long, learn to battery method is the most important!
A, battery solutions
Most laptop has the function of automatic frequency reduction, this advantage is maximum extended the notebook notebook battery usage time. Many use Celeron notebook may have doubt, our notebook without this function, is also not save electricity?
CPU is just a part of the power cost, in fact, electric sequence should be like this: LCD > CPU card (full) > > wireless card > CPU fan. That is to say, in addition to CPU besides, we can also from other aspects, maximum limit reducing power consumption.
In Windows XP control panel has a power management options, "power use plan", the LCD screen set in idle 10 minutes or so close the most reasonable, and a hard disk is to set in 15 minutes or more more appropriate. Hard drive moment start need certain power not to say, frequent start and stop to the hard disk drive damage is quite large. Of course you can manually close screen, most of the notebook is through the fn function keys + F3 to achieve.
Set LCD, hard disk of the closing time
If you want to further saving power, also need to adjust the operation of the system state, this is not the Windows XP can do. To Thinkpad as an example, the majority of notebook has own battery management software, general of the display screen can provide very brightness adjustment, although the brightest state can get the best visual effect, but it is very, very power consumption, therefore, edit the document or some other common application screen brightness adjustment to seven or more low six levels of the most appropriate. At the same time, the CPU can also set to best battery performance, the CPU fan operation set to "equilibrium" more reasonable.
Part of the low price notebook no battery management software (because there is no built-in power management chip), but can use general battery monitor software to manage the battery.
Examples of the use T43, run at full speed played on DVD, the life time of the battery is only 2 hours 37 points, and the optimized scheme using duration can achieve 3 hours 17 minutes or so, ascension is very obvious.
Set the screen brightness, CPU speed, fan speed
Second, the correct charging method
There are a lot of people use Dell Latitude D830 Battery, see power less than 100% began to charge, but it will accelerate reduce lithium battery power total capacity, last, the battery use time is short a lot, and life will shorten greatly. Accordingly, the proposal will charge limit in less than 10% followed by charging, also want to pay attention to not set too low, such as the use of the remaining 3% to imitation, this also is not scientific.
Power shortage alarm must set, generally less than 10% alarm for good, less than 3% of the serious alarm means the battery has been not enough to support the next boot into the system.
A lot of battery management software is the default start charging less than 96%, so that charging can damage cell, so be sure to change this setting. In addition, the best off charging, so we can play the role of curing the battery.
Three, discharge is necessary?
If the Dell Inspiron 1545 Battery in use for a long time electricity greatly reduced, can try to depth discharge to "save" it. This is a "dead straws when" method, less than as a last resort, had better not to do so. Discharge the simplest method is constantly to run the program, less than 3% of electricity after restart notebook into the BIOS vacancy operation, automatic power until so far. Then depth charge, charging time to achieve eight hours, but no more than 12 hours, so can make lithium battery restore some electricity.
